Two interchangeable non-afterburning turbo-jet engines R-95Sh with non-adjustable nozzle with downstream gearbox, with autonomous electric startup will be installed.

Sighting equipment:

Modernized sight ASP-17BTs-8М2 provides sighting while shooting, bombing and missiles launch at day time and at night time at visible ground and air targets;

Laser station of illumination and range-metering (Klen-PS) provides measuring of slant range to target when solving the sighting tasks and its sending to the sight, as well as to aim the guided missile with laser seeker;

System of audio-visual registration SAVR-25 (instead of SSh-45).

Flight and navigation equipment

The navigation system KN-23-1 is the key of flight and navigation equipment. It provides:

Radio technical equipment

Provides radio communication with ground objects and aircrafts in the whole altitude and range envelope.

Radio technical equipment consists of:

R-862 communication radio station upgraded to use the comm. channels with step 8.33kHz is designed for telephone radio communication in meter and decimetre wave range between the aircrafts and ground objects;

Radio station for communication with the army with frequency spectrum stipulated by the customer that provides radio telephone communication with control points and separate moving objects of the army;

A-511 airborne transponder instead of SО-69 designed for operation with secondary radar systems ATS RBS in modes А and AC according to ICAO requirements.

Aircraft defence means warn the pilot about aircraft exposure to radiation from ground radars of AAMSs and enemy’s fighters, radar bearing under different modes of irradiation, active jamming of weapon control radars, infrared jamming of missiles with heat-emitting homing heads.

Also during the overhaul, the BUR-4-1-10 digital flight data registration system will be installed instead of Теster-UZ.
